Dimmer switch Kontakt-Simon CS9LA.01/11 single-pole press-rotate for dimmable LED 230V white

Kontakt-Simon CS9LA.01/11 single-pole press-rotate dimmer is designed to control brightness of dimmable LED luminaires on 230V single-circuit installations. The device combines a momentary push action for on/off switching with a rotary control for smooth adjustment of light level. Finished in white, it fits standard European wall boxes and is intended for residential and light commercial environments where compatible LED fixtures require variable output.

Advantages

This dimmer offers combined push-button and rotary operation for intuitive control of lighting intensity and an integrated single-pole design suitable for one-circuit installations. It provides smooth adjustment of dimmable LED loads at mains voltage and a compact form factor that integrates with common wall-mount frames. The white finish ensures visual compatibility with modern interiors while the control mechanism supports gradual ramping to minimize flicker with compatible LED lamps.

Suitable for

• Dimming compatible LED downlights and ceiling luminaires on a single circuit
• Residential rooms such as living rooms, bedrooms and dining areas
• Light commercial spaces like offices, corridors and meeting rooms with compatible LEDs

Key specifications

• Control type: push-to-toggle (on/off) plus rotary dimming
• Poles: single-pole (controls one live conductor)
• Rated voltage: designed for 230 V AC mains
• Load compatibility: intended for dimmable LED loads (check lamp compatibility with phase-cut dimmers)
• Finish: white front and knob suitable for flush wall mounting
• Mounting: compatible with standard European recessed wall boxes and switch frames

How to use

Install the dimmer into a standard single-gang wall box following local electrical regulations and with the supply disconnected. Use the push action to switch the connected lighting on and off; rotate the knob to increase or decrease brightness smoothly. If replacing an existing switch, ensure wiring corresponds to a single-pole configuration and verify compatibility of LED luminaires with phase-cut dimming. After installation, power up and test across the full dimming range to confirm stable operation without flicker.

Usage recommendations

For reliable dimming performance, use with LED lamps and drivers labelled as compatible with leading-edge or trailing-edge (phase-cut) dimmers as appropriate. Avoid using with non-dimmable LED lamps. When in doubt, consult lamp manufacturer compatibility lists or perform a small-scale test before large installations. Ensure the total connected load falls within the dimmer’s supported range and follow local wiring standards during installation.
